The wide-spread use of the automobile for business and personal use has so congested traffic in our cities that the 
regulation of traffic has kecome a necessity. Before automobiles were so prevalent, a traffic officer, stationed at a street 
intersection, could easily direct traffic, and handle it so that there was little or no congestion, even during the rush hours 
The rapidly increasing use of the automobile has created a trafic problem, which can be solved properly only by regulating 
traffic, not merely at one or two of the main intersections but throughout the entire congested district. 

In order to move traffic quickly and smoothly, it is necessary for the traffic officers to work in unison. This can be 
accomplished only by providing an electrically interlocked system of traffic regulation. In short, a system of traffic signals 
is becoming an absolute necessity. In cities where they have already been installed, traffic is being handled much more 
quickly and smoothly, with a result that people are able to get through the congested traffic area in a much shorter time. 

The intelligent regulation of traffic not only saves considerable time and annoyance, but also prevents accidents. 
A properly installed and operated system of traffic signals, by which the signals are clearly displayed, and changed at 
predetermined intervals, is so simple that vehicle drivers and pedestrians can readily be governed by them. 

The Crouse-Hinds Company has developed such a system of traffic control, which has been installed in a great many 
cities and which is daily regulating traffic, so that it moves quickly and safely. This system of traffic control is based 
on displaying colored lights so that they are clearly visible during the day as well as at night. The colors adopted by 
the Crouse-Hinds Company for the regulation of street traffic are the standard steam railway signal colors and it is 
advisable that these colors be adhered to, so as to avoid confusion. These colors have come to mean something very 
definite in the minds of most people and if they are used universally there will be no confusion to people who drive their 
cars in other than their home city. These colors are: 


Green —‘‘Go”’ 
Amber —‘‘Caution”’ 
Red —‘‘Stop” 


The signal system is so designed and installed that when the green light is displayed along the street, traffic moves 
and at the same time traffic is stopped along all intersecting streets by displaying the red light on them. When it is desired 
to change the direction of traffic, the change is not made abruptly from green to red and from red to green, but a caution 
light, amber in color, is displayed for a few seconds. The displaying of the amber light provides a warning of an impending 
change in the direction of traffic and gives the vehicle driver and pedestrian sufficient time to cross the street if they 
have already started. 

The standard traffic signal, therefore, consists of three lights; green, amber, and red, which are lighted in a cycle from 
“oo” to “stop.” Below there are shown in color the signals during a complete cycle of operation. 


\ 


Caution Stop 


The switch which controls the signals is so designed that the contact arm overlaps the green and amber contacts and 
the amber and red contacts, making the change of direction gradually and providing a warning of the change. Many 
of the traffic signal systems already installed have a bell connected in multiple with the amber light, which provides an 
audible as well as a visual signal of an impending change in the direction of traffic. When the bell is used, it is usually con- 
nected on a separate bus-line and wired to the amber contact on the switch through a single-pole switch which may be 
opened when it is desired to leave the amber lights burning at night after the traffic system is turned off.

Below there are given several diagrams showing the locations of One-Way Traffic Signals on the near side of the street 
and on the far side of the street for regular and irregular corners. 

In cases similar to Figure 2 it is not possible to use any signal other than a One-Way Signal because the center of the 
circle is usually filled with a monument or flower bed. Then again there are many cases of two streets crossing at such 
an angle that a Four-Way Signal can be used to advantage and a third street coming in which must have a signal of its 
own, controlled by the one master switch. Figure 3 shows a typical irregular intersection of streets which is handled by 
a combination of signals.

Here are shown five streets coming together but the axis of the several streets do not cross at a common point. Due 
to traffic conditions it was impossible to locate a signal at the intersection of the axis of any two of the five streets. The 
position of the type TS-2 Traffic Signal out in the center of the street is the same as the old hand semaphore, which it 
replaced. This signal is visible in both directions along one street but it is not visible during the day on either of the 
other three streets. To control these streets, three of the type TS-4 One-Way Traffic Signals are used, and they are so 
located that they are in the direct line of vision of the traffic which they control. All of these signals are connected to 
and controlled by the master switch operated by the traffic officer.

Wiring 

The ordinary wiring of an electrically-interlocked traffic signal system presents no complications and is in reality quite 
simple. Where the system is designed to handle traffic along parallel and intersecting streets, only four wires are required 
for the control. Of these four wires, one is a common negative going to all the signal lamps. The other three are treated 
as positives. To the first of these there are connected all of the signal lamps which illuminate the green lenses facing north 
and south; also the red lenses facing east and west. To the second positive wire, there are connected all of the lamps which 
illuminate the amber lenses facing both north and south, and east and west. And to the third of these positive wires there 
are connected all of the lamps which illuminate the red lenses, facing north and south, and the green lenses facing east and 
west. 

These three positive wires are connected to the three segments of the master control switch; to the moving arm of which 
there is connected the main positive. As the moving arm of the master control switch is rotated from position to position, 
traffic is carried through a complete cycle of operation. With the switch in the first position, green lights are displayed on 
all north and south streets, which permits traffic to proceed and at the same time, red lights are displayed on all intersecting 
east and west streets, which stops that traffic. When the master control switch is in the second position, amber lights are 
displayed on all streets, both north and south, and east and west. This amber caution signal is displayed for five seconds, 
during which time moving traffic comes to a stop at the first intersecting cross street and stopped traffic prepares to move. 
This interval of five seconds, during which the amber caution light is displayed, is sufficient to clear the intersections 
of both vehicular and pedestrian traffic; and when the master switch is moved to the third position, traffic proceeds 
smoothly east and west. 

In most traffic signal installations, it is customary to use a bell in conjunction with the amber caution signal, thus pro- 
viding an audible as well as a visual signal of an impending change in the direction of traffic. The bell may be connected 
in multiple with the amber signal light In some installations of electrically-interlocked traffic signals, the amber caution 
signals are left burning all night after the signal system has been shut down. If this feature is desired, a fifth bus wire is 
necessary and the bells are connected to it. This bus wire is connected to the amber contact on the master switch through 
a Single-pole switch which breaks the bell bus wire when the amber lights are left burning all night. 

This is the simplest form of wiring which may be used, and it is usually sufficient for small installations. Larger 
installations require more flexible wiring and some of these problems will be discussed. 

When several parallel streets are controlled, the bus wires for all streets should be connected in multiple to the switch- 
board located at the main control station. If this is done, any individual street may be disconnected from the system and 
controlled independently. This should only be done in case of an emergency, since the system will work more smoothly 
if all the streets are controlled in unison. 

In extremely large installations it is sometimes necessary to have one or more of the principal intersections so wired 
that they may be disconnected from the system and controlled for a brief interval by the officer in charge of that intersec- 
tion. Such a scheme is advisable only in case of a fire or a riot or when necessary to straighten out a bad traffic jam. 

Some signal systems have been installed providing for displaying red signal lights in all directions simultaneously, in 
order to bring all traffic to a dead stop in an extreme emergency. The system may be wired so that this can be done 
either from the master control station or so that the officer in charge of any intersection may throw red signals at that 
one intersection without disturbing the rest of the system. 

The very troublesome left-hand turn can also be quite readily controlled by signals by making proper connections for 
it at each intersection. When traffic is proceeding north and south with the green signal lights and a vehicle wants to 
make a left-hand turn, he may do so safely by signalling the officer in charge of that intersection who can stop the opposing 
parallel stream of traffic by momentarily displaying a red light, and then returning to the green light after the left-hand 
turn has been completed. 

Any or all of these special features can be provided in any electrically-interlocked traffic signal system. The Crouse- 
Hinds Company will help any city solve its traffic problem. It will go into the problem thoroughly and submit a working 
plan, embodying any or all of the special features mentioned above.

The Crouse-Hinds Company has developed two new types of traffic signal units which are used to control traffic in 
four directions. They are for use at intersections where streets cross approximately at right angles and the signal units 
should be located as near as possible to the intersection of the axis of the streets. 

Each of these signals consists of three light-tight compartments mounted one above the other. On all four faces of each 
of the compartments there are 83-inch diameter lenses of the proper colors to control traffic in all four directions. The top 
compartment has green lenses on two opposite faces and red lenses on the other two. The bottom compartment is just 
the reverse of the top one, while the center compartment has amber lenses on all four faces. 

When the upper compartment is lighted, the green signal is displayed in north and south directions and a red signal 
is displayed in east and west directions. When the bottom compartment is lighted, red is displayed in north and south 
and green in east and west directions. The change in the direction of traffic is not made abruptly from one direction 
to the other because for a period of a few seconds the amber caution signal is displayed before the signal is given for a 
change in direction of traffic. This amber light gives a warning of the impending change in the direction so that traffic 
which is moving will stop at the first intersecting street and traffic which is stopped will get ready to move. The displaying 
of the amber caution light for a short interval gives sufficient time for a vehicle or pedestrian to complete a trip across the 
intersection and clears the intersection for traffic which is about to start. 

As in the ease of other signals it is advisable to connect a bell in multiple with the amber light to provide an audible 
as well as a visible signal of an impending change in traffic. On the post and bracket types of signals, it is customary to 
fasten the bell to the post or bracket which supports the signal, and these types are not furnished complete with bell. The 
mast arm and span-wire suspension types of signals can be furnished with or without the bell attached to the signal proper. 

Two different types of signals are furnished. In one of them, type TS-2, all four lenses in each compartment are lighted 
by a single lamp, usually a 150-watt lamp, though smaller lamps may be used. One lamp illtmminates all four lenses in the 
compartment. On the inner face of each of these signals there is a guard to prevent phantom signals and also a diffuser, 
which materially increases the visibility of the signal at the side. 

In the other type of signal, type TS-5, each of the lenses is illuminated by a separate lamp, there being twelve lamps 
in the signal. This signal is arranged to take a 50-watt, 115-volt, mill type Mazda lamp in a P-19 bulb. Back of each of 
these lamps there is a parabolic reflector which adds materially to the efficiency of the signal. 

With the TS-5 signal it is possible to get any combination of colors desired such as stopping traffic in all four direc- 
tions in an emergency, or stopping it in three directions to permit left-hand turns. Neither of these conditions can be 
handled with the signal which has a single lamp for illuminating four lenses. Not only is this signal more flexible, but it 
has the added advantage of being less troublesome in case of a lamp failure, since only one signal is affected rather than four. 

Type TS-5 signal can be furnished with plain optical semaphore lenses or with prismatic diffusing lenses. Where 
signals are placed quite far apart the signals with optical lenses should be used, but where signals are mounted at every 
intersection signals with the prismatic diffusing lenses will be the better, since they have a somewhat wider angle of visi- 
bility, and the long range given by the optical semaphore lenses is not required. 

Types TS-2 and TS-5 signals are listed for mounting in various ways to meet almost any condition. The bottom of 
the post type of signal is tapped for a 4-inch pipe. Where the shaft of the supporting post is larger, it is only necessary to 
use a reducing coupling. The bracket type of signal is furnished complete with 4-foot bracket arms and pole clamp for 
steel poles of any diameter up to and including 10 inches, or for fastening to wooden poles. Orders for bracket mounted 
signals must specify pole diameters and also whether or not the feed for the signals comes through the pole or on the out- 
side of the pole. Where the standard length bracket is used, no additional support is required. Where the bracket is longer 
than standard, additional support may be required, depending upon the conditions of installation. Prices do not include 
additional support. 

These signals are also furnished for mounting on the end of a 2-inch mast arm. This type of suspension is not rigid but 
is flexibly suspended by four short chains which will relieve the thread on the end of the mast arm of strains due to wind 
pressure. 

Often it is desired to mount a four-way signal on a span wire over the center of intersection. The span-wire suspension 
is for this kind of installation. The hook-clamp, which hooks over the span wire, is made to swivel so that the signal may 
be lined up along the axis of the intersecting streets regardless of the hang of the span wire. Signals for mast arm and span- 
wire suspension may be furnished complete with bell enclosed in a compartment in the bottom of the signal. 

Both of these types of signals are entirely weatherproof and are so designed that no water, dust, or dirt can get into 
the housings. The three compartments, as well as the top and doors, are made of cast aluminum of liberal sections which 
insure the necessary mechanical strength together with light weight. 

The doors which hold the lenses are gasketed and each door is held in place by four wing screws which facilitate the 
removal of a door for the inspection or removal of a lamp.

Types TS-6 and TS-7 Four-Way Traffic Signals are similar to TS-2 and TS-5 as listed and described on pages 9 to 11 
except that they have only two of the four-sided compartments. The upper compartments have green lenses in two opposite 
sides and red lenses in the other two, while in the lower compartment the arrangement is reversed. The amber caution 
signal is mounted on top and is a WV Condulet with amber Fresnel lens. The lens of the WV Condulet is provided with 
a hood which protects it and also increases the daylight visibility. 

When the upper compartment is lighted, the green signal is displayed in north and south directions and a red signal is 
displayed in east and west directions. When the bottom compartment is lighted, red is displayed in north and south and 
green in east and west directions. The change in the direction of traffic is not made abruptly from one direction to the

In the other type of signal, type TS-7, each of the lenses is illuminated by a separate lamp, there being nine lamps 
in the signal. This signal is arranged to take a 50-watt, 115-volt, mill type Mazda lamp in a P-19 bulb. Back of each of 
these lamps there is a parabolic reflector which adds materially to the efficiency of the signal. 

With the TS-7 signal it is possible to get any combination of colors desired such as stopping traffic in all four directions 
in an emergency, or stopping it in three directions to permit left-hand turns. Neither of these conditions can be handled 
with the signal which has a single lamp for illuminating four lenses. Not only is this signal more flexible, but it has the 
added advantage of being less troublesome in case of a lamp failure, since only one signal is affected rather than four.

ONE-WAY TRAFFIC SIGNALS 
Type TS-4 
Vertical Bracket Mounting Only Horizontal 


Type TS-4 One-Way Traffic Signal is a very flexible unit in that it can be mounted to take care of any given traffic 
condition. Since it is designed to take care of traffic in one direction only the signals can be read in but one direction. 
These signals can be used to excellent advantage on streets which cross at acute angles or where five or more streets intersect 
at a given point. In many of our cities several streets radiate from a square or circle where it is not possible to get a 
clear vision up and down the street. In such cases type TS-4 One-Way Traffic Signal is the only one which can be used. 

This type of signal consists of three light-tight compartments arranged for mounting on brackets to clamp on tubular 
steel or wooden poles installed on the sidewalk. The signal itself projects over the street and is readily visible to both 
pedestrians and drivers of vehicles. In each of these compartments there is mounted a reflector and a colored 83-inch 
diameter semaphore lens or prismatic diffusing lens. When the signals are placed quite far apart it is better to use type 
TS-4 signals with semaphore lens but when they are installed at every street intersection the signal with the prismatic 
diffusing lens will be better since it has a some-what wider angle of visibility. Standard colors are used, namely green, 
ae and “stop,’ 
adjusted for a 50-watt, 115-volt, mill type Mazda lamp in a P-19 bulb and the filament of this lamp is at the focal point of 


”) 7 


amber, and red, which mean “‘go,”’ “‘caution, respectively. The lamp receptacle in each compartment is 
both the lens and reflector. This combination of light source, reflector, and lens is such that the signal is visible over a 
very wide angle and for very great distances. 

Type TS-4 One-Way Traffic Signal can be supplied with the lenses arranged in either a horizontal or a vertical line. 
The horizontally mounted signal has one advantage over the vertically mounted signal where installed on hilly streets. 
The signal is arranged to turn on its axis and, therefore, the signal lenses can be elevated or depressed so as to be in direct 
line of vision of oncoming traffic. 

Type TS-4 One-Way Traffic Signal is furnished wired complete. The four leads are properly tagged and are brought 
out through the cover of a type C Condulet in the top of the arm. This Condulet is already furnished with a four-wire 
composition cover, but where leads are to be run through the pole from underground wiring a cast-iron dome cover and 
gasket will be supplied. 

These signals may be mounted on either the near or the far side of the street as is desired, though the far side of the 
street is preferable where possible, since in this position signals are a little more visible to drivers of vehicles who are stopped 
and waiting for the signal to change. Where signals are located on the far side of the street they should be high enough 
to be visible over the line of cross traffic. 

Where four type TS-4 One-Way Traffic Signals are used at the intersection of two streets, it is unnecessary for all 
of them to be equipped with bells. It is customary to use only one or possibly two bells at an intersection. The bells 
may be mounted either at the rear of the signal box or on the post which supports the signal. The latter is the better 
place for it since it is a little more accessible for adjustment. 

The casings of the type TS-4 signals are made of either cast iron or cast aluminum. The standard arm is 3 feet 3 inches 
for horizontal mounting and 4 feet for vertical mounting from the center line of the signal to the pole. The casings are 
entirely weatherproof and the doors are gasketed and held firmly in place by four wing screws. The entire signal is finished 
with black enamel which is baked after application. Type TS-4 signals are furnished complete with bracket arms and pole 
clamps. Where the standard length bracket is used, no additional support is required. Where the bracket is longer than 
standard, additional support may be required, depending upon the conditions of installation. Prices do not include addi- 


IMA 


tional support. 

The arms of the bracket are made of 2-inch pipe and are screwed into heavy iron brackets which may be had to 
clamp around tubular steel poles up to 10 inches in diameter or for fastening the signal to wooden poles by means of through 
bolts. All requisitions for type TS-4 Traffic Signals should specify the diameter of poles on which they are to be mounted. 

The lenses are tipped downward approximately five degrees which brings the entire main beam of light in direct line 
of vision. 

Hoods are placed over the signal lenses and are carefully designed to give a maximum of protection from the direct 
rays of the sun without in any way lessening the visibility of the signal. With these hoods in place it is impossible to get 
a phantom signal; that is, it is impossible to have the sun’s rays fall on a lens in such a manner as to make it appear lighted 
when it is actually out. The hoods are finished with two coats of weatherproof black enamel which is baked after appli- 
cation. Hoods are permanently mounted on the door frames and should always be used.

TRAFFIC SIGNAL UNITS 
Type RM 


With Semaphore Lenses or Prismatic Diffusing Lenses 


In some of our cities signal towers are used exclusively for controlling traffic and, when such towers are used, it is 
often possible to use individual signal units and mount them as desired, either on top or on the sides of the towers. Such 
installations are shown on pages 31 and 35. The installation at Knoxville, Tennessee, shown on page 35, is made with 
individual type RM signal units without hoods over the lenses while the installation at Augusta, Georgia, shown on page 
31, is made with the same units except that the lenses are equipped with hoods. 

These type RM signal units are ideally suited for traffic signal installations. They may be obtained with the various 
colored semaphore or prismatic diffusing lenses which have been established as standard. The lenses conform to the 
standard of the American Railway Association for color value and transmission and the colors are such that they are 
readily discernable both during the day and at night. There is no opportunity for mistaking the colors. The lenses are 
88 inches in diameter. 

The casings of type RM signal units are made of the best quality of cast iron, free from flaws and blow-holes and 
are protected by a coating of weatherproof enamel which is baked after application. The front door is gasketed and held 
in place by three eye-bolts with covered wing-nuts. The covered wing-nuts protect the end of the threaded eye-bolt so 
that the doors may be readily opened for the replacement of burned out lamps. 

The casings are equipped with #4-inch conduit hubs on the top and bottom for convenience in wiring and when so 
specified on the order the casings may be tapped on one or both sides for a 44-inch conduit. 

When type RM signal units are mounted on the face of a tower it is advisable to use three for each direction 
controlled; one each having green, amber, and red semaphore lenses. The amber light should be mounted in the middle. 
Some municipalities prefer to use only the main “Go” and “Stop” units on each face of the tower and to use two type 
WV or two type V Condulets with amber globes on opposite corners of the tower. Type RM signal units together with 
the Condulets listed on page 30 will give sufficient signal units for any desired installation. Condulets for ordinary wiring 
purposes and type V Condulets with other hub arrangements will be found in Condulet Catalog No. 2000. 

In many cities booths for traffic officers are located at traffic centers and sometimes the individual traffic signal units 
can be mounted on them to good advantage. When the booths are utilized the signal units should be mounted on a 
suitable frame on top in order for them to be visible over top of the cross line of traffic. 

When the signal units are mounted quite high the beams of light should be tilted downward a few degrees, which 
will increase their visibility. 

Hoods are placed over the signal lenses and are carefully designed to give a maximum of protection from the direct rays 
of the sun without in any way lessening the visibility of the signal. With the hoods in place it is impossible to get a 
phantom signal; that is, it is impossible to have the sun’s rays fall on a lens in such a manner as to make it appear lighted 
when it is actually out. The hoods are finished with two coats of weatherproof black enamel which is baked after application. 
The hoods are permanently mounted on the door frames and should always be used.

The manual control switch for controlling traffic signals is a dial switch which insures the proper cycle of operation. 
It is important that a change in the direction of traffic be made gradual, so as to provide a slight but necessary interval, 
during which a vehicle or pedestrian may complete the trip across the street intersections. The ‘‘amber’” contact on the 
manual switch is between the “red” and “green” contacts and, in passing from one to the other, the amber, warning light 
is shown for a few seconds. 

The manual switch is very simple and durable and will stand up in the severe service of changing the direction of 
traffic from a thousand to fifteen hundred times a day. It is easy to operate, since the contacts roll rather than slide. 
The switch proper is mounted in a heavy cast-iron housing which is weatherproof. On the bottom of the casing there 
is an opening to take the various hub plates shown on the following page so that the switch may be connected to a rigid 
conduit system. Unless a particular hub plate is specified switches will be furnished with type YY P74 which is a straight 
hub for 144-inch pipe. The price of the switch includes any one of the hub plates selected. 

The switch is operated by an exterior handle. The grip of this handle is made of polished brass and is of sufficient size 
so that a man may grasp it comfortably with a gloved hand. On the outside of the casing there are marks to indicate the 
position of the switch. The switch cannot be tampered with as it is entirely enclosed in an iron housing. When the 
traffic signal system is turned off at night the master switch is set on the amber contact and locked in position. 

The switch is just as rugged electrically as it is mechanically. The rolls and corresponding contacts are made of bronze. 
The contacts are notched to fit the rolls; consequently it is an easy matter to set and hold the switch in the proper 
position. Rolling contacts are better than sliding contacts, as wear is reduced to a minimum and the are does not always 
break at the same place. If, after a long period of service, the rolls or contacts need renewing, it can be done easily and 
quickly. The rolls themselves can be replaced without the use of tools and the contacts can be replaced from the face 
of the switch by removing two nuts. 

The switch has a rating of 15 amperes at 125 volts. Two different manual switches are listed. One of these switches 
is intended to control one or more individual signals, and mounted in the case of this manual switch are three snap- 
switches and a set of fuse-clips. The fuse-clips and one of the snap-switches are for the main line, the second snap- 
switch is to break the bell circuit when the amber signals are left burning after the traffic system is turned off, and the 
third snap-switch is used in the circuit of the light above the officer’s head on post type of signals only. 

In the other type of manual switch the snap-switches and fuse-clips are omitted as this switch is intended for use 
in connection with a main switchboard mounted in the control tower. 

The two standard manual switches are intended to control four-way traffic; that is, traffic at two intersecting streets. 
When there are three intersecting streets or two intersecting streets and a third dead end street, the contacts on the 
standard manual switch can be modified to take care of such a condition when it is desired to permit traffic to proceed on one 


street at a time.

AUTOMATIC TIMING SWITCHES 


15-Ampere, 125-Volt, 60-Cycle, A. C. 
Single Cycle Indoor Operation Double Cycle 


Automatic Timing Switch Enclosed in Weatherproof Box 
(Broken-away View) 


In large installations of electrically interlocked street traffic signals it is often advisable to use an automatic switch for 
timing the changes in traffic. Automatic switches can be made for any desired cycle of timing and insure constant, 
accurate timing of the signal system. Furthermore, when an automatic timing switch is used, the operator in charge of 
the signal system is relieved of the usual manual operation. 

Automatic Timing Switches are listed for use on 125-volt, 60-cycle, alternating current circuits and have a capa- 
city of 15 amperes. When the current of the traffic signal system is greater than 15 amperes, remote-control, magnetic 
switches must be installed between the control switch and the line. If the circuit voltage and frequency is other than 125 
volts and 60 cycles the requisition must so state, otherwise switches having this rating will be furnished. 

The correct cycle of time for traffic in both directions should be determined by actual study of the traffic zone. It 
may be found that this cycle, during the rush-hour traffic and non-rush-hour traffic, is different, and if so, provision should 
be made to take care of it. A cycle of timing frequently used for traffic in medium-sized cities is sixty seconds along the 
main artery of traffic and thirty seconds for cross traffic. The amber light which shows between the two main colors should 
be of five seconds duration and should overlap two seconds, thus making the total period of the traffic cycle 60 -+80+3 +3 = 
96 seconds. This, or any other interval, can be timed accurately with a motor-driven, automatic timing switch. 

During the rush hour when traffic is densest it is often advisable to materially increase the cycle of timing and this 
is sometimes just double the regular cycle. The two cycles of timing can be accomplished with one double-cycle switch, 
but it is better to use two separate single-cycle switches, since one or the other then may be disconnected for inspection and 
repairs when necessary. 

In some cities the automatic switch is designed to take care of the rush-hour traffic and the rest of the time the system 
is manually controlled. 

In connection with all automatic timing switches, whether single or double cycle, it is advisable to use a manual switch 
so that any unusual conditions such as fires, parades, etc., may be taken care of. The two switches are wired as shown on 
pages 27 and 28 and either one or the other may be used at will. 

The wiring diagrams given in this catalog on pages 24 to 28 show automatic timing and combined automatic and 
manual timing. They are the simplest schemes and the ones most generally used. They will suit the majority of 
cases, but where special local conditions warrant the use of other, more complicated connections, the Crouse-Hinds 
Company is always willing to assist in the solution of these special problems. 

These timing switches are all listed for indoor operation but, if specified on the order, a weatherproof box, made of 
fourteen-gauge sheet iron, black-enameled, can be furnished. It is advisable, however, to mount the switch indoors so 


that it may receive periodic inspection.

Manual Control 
60, 100, and 150-Ampere Capacity at 125 Volts 


Switches for manual control will carry a load of fifteen amperes at one 
hundred and twenty-five volts. When the number of signals connected to a SYS- 
tem does not exceed this current it is unnecessary to use a switchboard with re- 
mote control, magnetic switches. In most cases where electrically-interlocked 
traffic signals are used to control one or more streets, it is necessary to use a 
switchboard with remote-control, magnetic switches. 

This switchboard has the following material mounted on it: 

1 double-pole, single-throw, fused main line switch. 

4 single-pole, single-throw, remote-control, magnetic switches. 
3 double-pole, double-throw, change-over switches. 

1 single-pole, single-throw, bell switch. 

Only three remote-control, magnetic switches are required for the normal 
operation of traffic signal circuits but all of these switchboards are equipped with 
four. They are connected with three double-pole, double-throw, change-over 
switches, so that the extra magnetic switch can be thrown in place of any one 
of the three regular magnetic switches which may require adjustment. Under 
normal conditions the three double-pole, double-throw, change-over switches 
are thrown to the left. When any one of the three regular magnetic switches 
requires adjustment, the corresponding double-pole, double-throw, change-over 
switch is thrown to the right, which cuts out the regular magnetic switch and 
throws the extra one in its place. 

The panels of these switchboards are the best quality of oiled Monson Slate. 
They are mounted on angle iron supports for floor mounting, and equipped with 
back braces 36 inches long. All switchboards are wired complete.

over switches, so that the extra magnetic switch can be thrown in place of any 
one of the three regular magnetic switches which may require adjustment. 
Under normal conditions the three double-pole, double-throw, change-over 
switches are thrown to the left. When any one of the three regular magnetic 
switches requires adjustment, the corresponding double-pole, double-throw, 
change-over switch is thrown to the right, which cuts out the regular magnetic 
switch and throws the extra one in its place. 

SAR eae ee ee The panels of these switchboards are the best quality of oiled Monson Slate.

Two Cycles of Timing back braces 36 inches long. All switchboards are wired complete.

The use of bells in traffic signal systems is a matter for local decision. The bell is usually wired in multiple with the 
amber or warning light, in order to give an audible as well as a visual signal of an impending change in the direction of 
trafic. ‘The bells are, however, usually connected to a separate bus line, through a single-pole switch from the amber 
contact on the control switch or from the amber magnetic switch, so that the bell circuit may be broken when necessary. 
In many cities the amber caution signals are left burning after the traffic signal system has been shut down for the night 
and under this condition it is necessary to disconnect the bell circuit. 

The Crouse-Hinds Company does not manufacture bells, but, if specified on the order, it is in a position to furnish 
reliable bells. The extremely severe conditions of traffic signal service makes it imperative to use a very rugged bell. 
Our experience has been that it is impossible to use any bell in which there are interior contacts for interrupting the 
circuits since such bells will not stand up in service due to the very rapid burning of these contacts. The bells listed in 
this catalog are of the electro-magnetic type and have been found very satisfactory. 

The bells should be mounted in an accessible place, so that they may be periodically inspected and adjusted when 
necessary.

CONDULETS FOR USE WITH TRAFFIC SIGNALS 


lis 


In making up traffic signals from the individual parts, it is sometimes desired to use standard Condulets for the amber 
or caution light. Below are listed three types of Condulets. Types V, VA, and WV are the types most generally used. 
These Condulets are listed in Condulet Catalog No. 2000 and Condulet discounts govern them. Types V and VA 
Condulets will take a 60-watt B lamp or a 75-watt C lamp. It is recommended that the 75-watt C lamp be used. Type 
WV Condulet will take up to a 150-watt C lamp, but a 75-watt C lamp will be large enough. When ordering the WV Con- 
dulet it is necessary to specify the size lamp to be used so that the lamp receptacle may be properly adjusted to bring 
the lamp filament on the center line of the Fresnel lens. 

The bodies of these Condulets are made of cast iron, with black enamel finish. If galvanized Condulets are wanted 
the order should so specify.
